A routine maintenance schedule must be actively pursued in order to help achieve and maintain water chemistry. Initially, pool maintenance may seem complicated and time-consuming. But, once routine maintenance becomes an integrated part of your life as a pool owner, it will be very easy to maintain your pool. Furthermore, as you continually engage in pool maintenance, you will begin to develop an understanding of your personal pool needs.
Once your pool is clean, clear, blue, and sparkling, it becomes much easier to maintain. It is always easier to maintain a pool and prevent problems than it is to rectify problems. With far less time and effort, as well as money, you can maintain your pool and keep it inviting all season long. Due to varying bather loads from pool-to-pool and varying climates from region-to-region, poolmanual.com cannot provide a universal maintenance schedule. You must recognize your personal pool needs and you must budget your time in order to follow a routine maintenance schedule that works best for you and your pool. Poolmanual.com will provide the necessary maintenance tasks that do need to be pursued. While it is not absolutely mandatory to follow these procedures step-by-step, the following is a well-recognized pool maintenance schedule, regardless of your region:
- Test water - but do not add chemicals until the maintenance schedule for that day is complete.
- Use your net(s) - remove all leaves and other large debris from the pool.
- Use your brush - remove dirt, or perhaps algae, stains, or scale from the pool walls and floor.
- Clean all baskets - for the skimmer(s) and the pump.
- Vacuum - remove any settled and remaining dirt, leaves or other debris from the pool.
- Clean the filter - if it is a sand filter or a DE filter, then backwash. If it is a cartridge filter, then rinse the individual pleated filter elements with a garden hose and a pressurized nozzle.
- Add the necessary chemical(s) - from the test(s) taken earlier that day.
- Shock regularly
You will have to create your own maintenance schedule. Poolmanual.com does not want to tell you to do "this" on this day and "that" on that day. With your bather load and with your climate, routine maintenance is very individualized. Poolmanual.com will provide an in-depth explanation of the various maintenance tasks, and you will have to create your own maintenance schedule, always compensating for climate and bather load.
For more specific information on routine maintenance, select from the following topics:
NETTING: There are two styles of standard pool nets:
- The deep leaf net (also called a leaf rake)-has a wide opening and a deep net. This style of net is primarily used to reach leaves or large debris that have settled to the pool floor. The deep leaf net can also be used to skim leaves and debris off the surface of the water, but the skimmer net is best at performing this task.
- The skimmer net has a shallow net and is primarily used to remove leaves, grass clippings, debris, or insects that float on the surface of the water.
Regardless of the net used, leaves and debris must be removed from the pool for a number of reasons. A collection of leaves and debris on the pool floor very well may clog the main drain, which will restrict water circulation and filtration. Leaves and debris can also clog the skimmer basket(s), which will restrict water circulation. Leaves and debris will also absorb chlorine (or its alternative), rendering it less effective to keep up with the bacteria, living organisms, ammonia, and other contaminates that are constantly present in pool water. Leaves and debris may also contain algae spores, which can lead to an outbreak of algae. Leaves and debris can also clog vacuum equipment. It is best to net out as much of the larger leaves and debris as possible, and then vacuum the rest.
It is important to routinely net leaves and debris out of the pool. Netting literally takes 10 - 15 minutes, and should be done anytime a significant amount of leaves or other debris are present in the pool. Netting should be performed after any windstorm. Netting should be performed daily during autumn, and perhaps multiple times per day on any windy autumn day.
BRUSHING: Pool Brushes are typically 18" long and have either durable nylon bristles (to be used on any type of pool) or stainless steel bristles (to remove algae, stubborn dirt, stains or scale on concrete, gunite, shotcrete, or fiberglass pools).
Brushing is an extremely important, but often overlooked, task towards maintaining your pool. Brushing will remove microscopic matter from the pool walls and floor, suspend this matter in the water, where they will be killed by chlorine (or its alternative) and filtered out of the pool. NOTE: If the microscopic matter is too small and remains in the pool, you will need to add a Clarifier to coagulate these small particles into larger particles, where they will indeed be killed by chlorine (or is alternative) and trapped by the filter.
Always brush the pool from the walls to the floor, using a top to bottom brush technique. Start at the shallow end and brush towards the deep end. Brushing takes no more than 10 - 15 minutes of work, and should be accomplished at least twice per week (and perhaps more often if landscaping or construction are underway near your pool). You should also make sure to brush the day before vacuuming the pool. When you do this, make sure the equipment is operational for a couple hours after brushing so that the main drain and skimmer(s) can remove the recently brushed dirt and debris from the pool. Then, shut "off" the equipment overnight-vacuuming should be accomplished after the water has been calm for several hours so that any dirt and debris that remains in the pool can settle to the bottom in order to be vacuumed out of the pool. Then, that next morning, restart the equipment and vacuum the pool. After the vacuum, monitor the pressure guage-if it is 8-10 psi above the standard operating pressure, clean the filter.
Brushing is the one of the easiest items of the maintenance schedule. If, however, brushing is neglected and favorable conditions should allow for an outbreak of algae, brushing will need to be done daily, and perhaps multiple times per day, and it will be time-consuming and labor-intensive. Therefore, makes sure brushing is part of your routine maintenance schedule.
SKIMMER BASKET(S): At times, the pressure gauge on your filter will show the operating pressure to be low, which will cause circulation to be poor. The first area to check is to make sure the water level in the pool is adequate. If not, fill the pool to the standard operating level (halfway up the skimmer). If the water level is adwquate, check and clean the skimmer basket(s). Some pools have only one skimmer, while most pools have at least tow skimmers. Here are the steps to clean your skimmer basket(s):
- Remove lid from the skimmer. This lid will be on your pool deck. If there is no lid to access the skimmer basket from the top, simply kneel down, stabilize yourself on the deck, and remove the skimmer basket from the skimmer opening inside the pool. If you cannot access the skimmer basket from your pool deck and have to get it from the skimmer opening inside the pool, be careful not to fall into the pool.
- Remove the basket from the skimmer.
- Empty out all the contents.
- Spray the basket with a garden hose and nozzle.
- Put the basket back in the skimmer.
- (If you accessed the skimmer from the opening on your pool deck, put the lid back on the skimmer).
NOTE: For aboveground pools, you can remove the lid to the skimmer box that is mounted on the outside of the pool wall. Once removed, you will have easy access to the skimmer basket.
Notes:
- If there is more than one skimmer, repeat the process for all skimmers.
- If skimmer basket(s) are extremely full, it is a good idea to shut "off" the equipment TEMPORARILY in order remove the basket(s) from the skimmer(s) without damaging them.
- In autumn, when leaves are falling at a rapid and continual pace, it is a good idea to turn the skimmer valve(s) to the "closed" position in order to temporarily end skimming. This way there is no chance that leaves or debris can enter the plumbing where they could clog the plumbing. Once all baskets are cleaned and put back in place, make sure to turn the skimmer valves back to the "open" position.
NOTE: For an aboveground pool, you can put a plug (either threaded or expandable) or a tennis ball in the plumbing outlet on the bottom of the skimmer.
CLEANING THE PUMP BASKET: A pump basket will sit in the pump housing-the front part of the pump. Your pool will also have a skimmer basket in each of the skimmers. It is the job of these skimmer baskets to trap leaves and other debris so that they do not enter the plumbing. At times, though, some debris (particularly pine needles, dog hair, and other small debris) will escape the simmer basket(s) and will enter the plumbing. If this occurs, it is the job of the pump basket to trap this debris before it enters the equipment, where real damage could occur. Like the skimmer basket(s), the pump basket has very fine passages that will trap dirt or debris, but allow water to pass through. The pump basket is usually positioned under s clear lid, so you can literally see if it contains any debris. You will have to monitor the pump basket daily and clean it out whenever needed. Follow these step to clean your pump basket:
- Turn "off" the power to the equipment temporarily.
- Turn the valves (main drain and skimmers) to the "closed" position.
- Remove the lid from the pump housing-the front part of the pump.
- Remove the basket from the pump.
- Empty out any contents.
- Spray the basket with a garden hose and nozzle.
- Put the basket back in the pump.
- Make sure the O-ring on the pump lid is in place. Approximately once per month, or as often as it is needed, put a lubricant on the O-ring. It will help seal the lid (to prevent the entrance of any air into the pump) and it will add to the life of your pump lid O-ring. Any pool professional can sell you the lubricant.
- Put the pump lid back on the pump.
- Turn the valve for ONLY the main drain back to the "open" position.
- Turn the equipment "on" immediately. The entire process FROM turning "off" the equipment TO turning it back "on" should take you no more than 1 minute.
- If pump does not start after approximately 1 ½ minutes, you need to prime
the pump.
- If pump does start, open the skimmer valve(s). Open each skimmer valve one at a time, and slowly to alleviate all the air. If there is more than one skimmer, open each one slowly.
NOTE: Most aboveground pools do not use any valves. The few that do include a slide valve before and after the pump.
Notes:
- Do not assume skimmer basket(s) will catch all leaves or debris. Check the pump basket just as often as the skimmer basket(s), and when needed, clean all the baskets. Even if every basket had to be cleaned, the entire process would take you less than 5 minutes.
- It is a good idea to have an O-ring lubricant in stock.
VACUUMING "ON FILTER": During a routine vacuum, with a manageable amount of dirt or debris in the pool, vacuum with the multiport on "filter." This will vacuum the dirt and debris to the filter where it will be trapped and permanently removed from the pool. Only clean water will return to the pool. Here are the steps:
- The night before you vacuum, brush the pool walls and floor.
- After brushing, allow the equipment to be operational for at least 2 hours. This will allow the main drain and skimmer(s) to remove the recently brushed and currently suspended dirt and debris. Then, turn "off" the equipment overnight to allow any remaining dirt and debris to settle to the pool floor.
- The day of the vacuum, make sure the water level in the pool is to the standard operating water level-half way up the skimmer.
- Make sure the multiport is on the "filter" position. If for some reason it is not, with the equipment still "OFF," move the multiport handle to "filter."
- Turn the equipment back "on."
- Isolate the suction to the skimmer (or the designated vacuum line) that you will use for the vacuum. If you use a skimmer, close the valve for the main drain and the valve(s) for any other skimmer(s) that you will not be using for the vacuum. If you use a designated vacuum line, close the valves for the main drain and all skimmers.
- Install a telepole to your vac head.
- Install one end of the vacuum hose to the vac head.
- Allow the vac head (with one end of the vacuum hose and the telepole attached) to sink to the bottom of the pool in the deep end.
- Stretch the remaining vacuum hose along your pool deck.
- Where the vacuum hose meets the surface of the water, push the remaining vacuum hose from your deck downward (into the water) and inward (toward the wall). Only allow the end that will attach to your skimmer (or designated vacuum line) to be out of the water. This will eliminate air from the vacuum hose and fill it with water. Be careful not to fall into the pool.
- Once completely filled with water and primed, install the end of the vacuum hose into the skimmer (or designated suction line) that you will vacuum from. If you use your skimmer, poolmanual.com recommends that you purchase a vacuum seal plate to help hold in the suction.
- With the telepole, maneuver the vac head across the pool floor.
Notes:
- As you vacuum the pool, dirt and debris will get trapped in the filter. This, of course, will cause the pressure to rise within your equipment. Monitor the pressure gauge. If the pressure is 8-10 psi above the standard operating pressure, then clean the filter, regardless if you are still vacuuming or if you are complete.
- Vacuum slowly. You do not want to stir up the dirt and debris from the floor.
- Some pool professionals will advise you to hold the end of the vacuum hose in front of a return jet in order to prime the hose (eliminate air and fill with water). This is a good idea in theory. But, if dirt and debris is light, the water going from the return jet, through the vacuum hose, and out of the vac head could stir up this dirt and debris on the floor, clouding up the water, impairing visibility to effectively perform the vacuum. The objective when vacuuming is to have the dirt and debris settled on the floor-not stirred up and suspended in the water.
VACUUMING "TO WASTE": Sometimes dirt and debris will be thick and heavy. If so, do not vacuum to "filter" because pressure will build up so quickly that you will spend more time cleaning the filter then you will vacuuming. Rather, bypass the filter and vacuum with the multiport on "waste" (or "drain"). Remember to turn the equipment "off" when moving the multiport from "filter" to "waste" (or "drain"). Do not spend too much time vacuuming to "waste." When vacuuming to "waste," you will be sending the water to a waste-line, thus removing the water from the pool. Here are the steps:
- Raise the water level to the highest point of the pool. Fill the water level so high that you nearly overflow the pool.
- Make sure the multiport is on the "waste" (or "drain") position. If it is not, make sure to turn "off" the equipment before moving the multiport handle.
- Once on "waste" (or "drain"), and with the heightened water level, turn the equipment back "on."
- Isolate the suction to the skimmer (or the designated vacuum line) that you will use for the vacuum. If you use a skimmer, close the valve for the main drain and the valve(s) for any other skimmer(s) that you will not be using for the vacuum. If you use a designated vacuum line, close the valves for the main drain and all skimmers.
- Install the telepole to the vac head.
- Install one end of the vacuum hose to the vac head.
- Allow the vac head (with one end of the vacuum hose and the telepole attached) to sink to the bottom of the pool in the deep end.
- Stretch the remaining vacuum hose along your pool deck.
- Where the vacuum hose meets the surface of the water, push the remaining hose from your deck downward (into the water) and inward (toward the wall). Only allow the end that will attach to your skimmer (or designated vacuum line) to be out of the water. This will eliminate air from the vacuum hose and fill it with water. Be careful not to fall into the pool.
- Once completely filled with water and primed, install the end of the vacuum hose into the skimmer (or designated suction line) that you will use to vacuum. If you use your skimmer, poolmanual.com recommends that you purchase a vacuum seal plate to help hold in the suction.
- With the telepole, maneuver the vac head across the pool floor.
- Vacuum only until the water level drops just above the bottom of the skimmer (or just above the bottom of the designated vacuum line). Then stop; NEVER let the water level drop to or below the skimmer (or designated vacuum line). If you do allow the water level to get too low, air will get into the system which may cause you to lose prime or worse, which may cause your motor to overheat, become prematurely defective, and require a replacement, which is expensive.
Notes:
- When you vacuum to "waste" (or "drain"), it is a good idea to have a running garden hose in the skimmer that you are vacuuming from in order to help compensate for water that is lost through the waste-line during the vacuum. If you use a designated vacuum line, put the garden hose anywhere.
VACCUMING AN ABOVEGROUND POOL: During a routine vacuum, with a manageable amount of dirt or debris in the pool, vacuum with the multiport on "filter." This will vacuum the dirt and debris to the filter where it will be trapped and permanently removed from the pool. Only clean water will return to the pool. Here are the steps:
- The night before you vacuum, brush the pool walls and floor.
- After brushing, allow the equipment to be operational for at least 2 hours. This will allow the skimmer to remove the recently brushed and currently suspended dirt and debris. Then, turn "off" the equipment overnight to allow any remaining dirt and debris to settle to the pool floor.
- The day of the vacuum, make sure the water level in the pool is to the standard operating water level-half way up the skimmer.
- Make sure the multiport is on the "filter" position. If for some reason it is not, with the equipment still "OFF," move the multiport handle to "filter."
- Turn the equipment back "on."
- Increase the suction to the skimmer by using a vacuum seal plate. Place the vacuum seal plate over the skimmer basket.
- Install a telepole to your vac head.
- Install one end of the vacuum hose to the vac head.
- Allow the vacuum head (with one end of the vacuum hose and the telepole attached) to sink to the bottom of the pool.
- Stretch the remaining vacuum hose over the pool wall and into the yard. If you have a deck around your aboveground pool, stretch the vacuum hose along the deck.
- Where the vacuum hose meets the surface of the water, push the remaining vacuum hose downward (into the water) and inward (toward the wall). Only allow the end that will attach to your skimmer to be out of the water. This will eliminate air from the vacuum hose and fill it with water.
- Once completely filled with water and primed, install the end of the vacuum hose into the skimmer. Again, poolmanual.com recommends that you purchase a vacuum seal plate to help hold in the suction.
- With the telepole, maneuver the vac head across the pool floor.
Notes:
- As you vacuum the pool, dirt and debris will get trapped in the filter. This, of course, will cause the pressure to rise within your equipment. Monitor the pressure gauge. If the pressure is 8-10 psi above the standard operating pressure, then clean the filter, regardless if you are still vacuuming or if you are complete.
- Vacuum slowly. You do not want to stir up the dirt and debris from the floor.
- Some pool professionals will advise you to hold the end of the vacuum hose in front of a return jet in order to prime the hose (eliminate air and fill with water). This is a good idea in theory. But, if dirt and debris is light, the water going from the return jet, through the vacuum hose, and out of the vac head could stir up this dirt and debris on the floor, clouding up the water, impairing visibility to effectively perform the vacuum. The objective when vacuuming is to have the dirt and debris settled on the floor-not stirred up and suspended in the water.
- You can vacuum your aboveground pool "to waste" by filling up the water level to the highest point of the pool (almost to the point that the pool will overflow), connecting your backwash hose to the appropriate plumbing outlet on the equipment to create a manual waste-line, and by moving you multiport handle to the "Waste" (or "Drain") position; make sure that the power to your equipment is "OFF" before moving the multiport handle. Have a running garden hose over the pool wall to compensate for the water loss. Only vacuum "to waste" until the water level is just above the bottom of the skimmer opening inside the pool.
CLEANING A SAND FILTER: If you have a sand filter, it will need to be backwashed when the pressure is 8-10 psi above the standard operating pressure. Here are the steps:
- Turn "off" the equipment.
- Move the multiport handle from "filter" to "backwash".
- Turn "on" the equipment.
- Allow the equipment to backwash for 2 - 3 minutes. If your filter is equipped with a sight glass, backwash until the water in the sight glass turns from dirty to clean. When you backwash, you will sacrifice some of your pool water-chlorinated (or its alternative) pool water. Monitor the level of your chlorine (or its alternative) after a backwash. Also, monitor the water level. If it gets low, add water until the water level is at least half way up the skimmer.
- After backwashing, turn "off" the equipment.
- Move the multiport handle from "backwash" to "rinse".
- Turn "on" the equipment.
- Rinse the sand for 20 - 30 seconds to assure that all dirt and debris has been eliminated from the fresh sand.
- Turn "off" the equipment.
- Move the multiport handle from "rinse" back to "filter".
- Turn "on" the equipment and operate as normal.
Notes:
- Sand should be professionally replaced every 4-5 years. After this 4-5 years, once filter cycles decrease (when it is taking less time for the pressure guage to show a rise of 8-10 psi) and the need for backwashing increases, contract your local pool professionals and pay them to change the sand. There are fragile laterals at the bottom of the inside of your sand filter. If even one of these laterals is cracked or broken, sand will enter the pool, resulting in additional service-and additional fees. Therefore, have the sand professionally replaced.
- You can prolong a filter sand change by adding a specially formulated Sand Filter Cleaner during the 3rd or 4th year. Read the instructions on the label before adding any chemical/cleaner.
- Poor water chemistry, as well as insufficient cleaning of the filter, can lead to problems with the sand. Mudballs may form due to poor water chemistry, particularly a high pH. If your water is high in pH, it will not be able to keep calcium in solution. This calcium will find its way into the filter. This calcium can attach to the sand and combine with hair, lint, and other debris (due to a poorly cleaned filter) and form the mudballs, which can again attach to other mudballs to form even larger mudballs, resulting in a blockage in the filter. This can further lead to calcification of the sand. Another potential problem is channeling. If water chemistry or filter cleaning are further neglected, channeling may occur, creating a trail through the sand. During filtration, water will pass through the filter, but the dirt and debris will make its way through the channel, never coming in contact with the sand, and will re-enter the pool. Monitor your water chemistry and clean your filter.
CLEANING A DE FILTER: If you have a DE filter, it will need to be backwashed when the pressure is 8-10 psi above the standard operating pressure. The main drawback of backwashing with DE filters is that as the dirt and debris are removed from the filter, so is the DE powder. This requires adding new DE powder after each backwash. New style DE filters, called Regenerative DE filters, have implemented a "bump" mode in order to prolong the filter cycles and reduce the need to backwash. But, after so many "bumps," backwashing is inevitable. Here are the steps:
- Turn "off" the equipment.
- Move the multiport handle from "filter" to "backwash"
- Turn "on" the equipment. Allow the system to backwash for 2-3 minutes. If your filter is equipped with a sight glass, backwash until the water in the sight glass turns from dirty to clean. When you backwash, you will sacrifice some of your pool water-chlorinated (or its alternative) pool water. Monitor the level of your chlorine (or its alternative) after a backwash. Also, monitor the water level. If it gets low, add water until the water level is at least half way up the skimmer.
- Turn "off" the equipment.
- Move the multiport handle from "backwash" to "rinse."
- Turn "on" the equipment.
- Rinse the new layer of DE powder for about 10 seconds to assure that all dirt and debris have been removed from this new DE powder.
- Turn "off" the equipment.
- Move the multiport handle from "rinse" to "filter."
- Turn "on" the equipment.
- Add new DE powder
- Mix DE powder in a bucket of water, following the manufacturer's directions.
- Pour the DE powder/water mixture into a skimmer. The mixture will enter the DE filter and disperse evenly to create a fresh layer of DE powder on the DE grids. The DE powder forms what is called a filter cake on the grids.
- Too much DE powder can cause the filter cake to be too thick. The grids will compress against each other, casing an adhesive of the dirty DE powder to the grids. If this occurs, you would be wise to contract and pay your local pool professionals to scrape the dirty DE powder off the grids; care must be taken so that the grids are not torn.
- Too little DE powder can cause dirt and debris to get imbedded on the grids, which will ruin the grids.
Notes:
- New style DE filters, called Regenerative DE filters, require less backwashing, as they can be "bumped" to readjust DE powder, which prolongs the filter cycle. Here are the steps to "bumping":
- When the pressure is 8-10 psi above the standard operating pressure, close all the valves (main drain and skimmers) and turn the equipment "off" for at least 2-3 minutes
- Most Regenerative DE filters have a "bumping handle." By slowly pulling down and rigorously pushing up on the handle 5-10 times, DE powder will fall to the bottom of the filter
- When 5-10 bumps are completed and 2-3 minutes have elapsed, open all of the valves and turn the equipment back "on", and a fresh layer of DE powder will instantly form on the DE grids inside your DE filter.
- A Regenerative filter can only be bumped so many times before backwashing is inevitable. Once filter cycles decrease and the need to "bump" increases, backwash the filter and add new DE powder, using the same sequence of steps as above.
- If your Regenerative DE filter is not equipped with a "bump handle," simply hit the actual filter tank/body with a rubber hammer 5-10 times.
- Check the DE grids inside your DE filter periodically. Cleaning the grids is required periodically because (body or suntan) oils, scale, and other deposits can build up on the grids. Many pool professionals sell a specially formulated Filter Cleaner for DE grids. If the grids are torn or frayed, have your local pool professionals install new DE grids for you.
CLEANING A CARTRIDGE FILTER: If you have a cartridge filter, the individual pleated filter elements will need to be removed from the filter itself, cleaned with a garden hose and pressurized nozzle when the pressure is 8 - 10 psi above the standard operating pressure, and secured back in the filter. There is no backwashing with a cartridge filter. Here are the steps to clean a cartridge filter:
- Turn "off" the equipment.
- Remove the lid to the filter tank. Many Cartridge filters have a band that holds the lid of the filter to the base of the filter. If your cartridge filter uses a different application, or if you have difficulty removing the lid for any reason, consult your local pool professionals for advice.
- Remove the pleated filter element(s) from the filter. Some cartridge filters use only one large pleated filter element, while other cartridge filters use a series of smaller pleated filter elements.
- Spray each pleated filter element with a garden hose and pressurized nozzle. Take time to spray between each pleat, as this is where dirt and debris will collect.
- Put the filter element(s) back in the filter.
- Put the lid back on the filter tank and secure the lid. Make sure the large O-ring is in place and is in good working shape. About once per month, or whenever needed, put an O-ring lubricant on the O-ring. This will create a tight seal, eliminating any air from entering the filter. This will also extend the life of your O-ring. If the O-ring is torn or frayed, or in any way unusable, then purchase a new O-ring from your local pool professionals.
- Turn "on" the equipment and operate as normal.
Notes:
- The individual pleated filter element(s) should be replaced yearly. A benefit of cartridge filters is their filtering capabilities and the ease in which they are cleaned. A drawback of cartridge filters is the expense of replacing pleated filter elements each year. But, if the pleated filter elements are still in relatively good shape, store them and keep them as a backup while your main pleated filter element(s) are being cleaned.
- You can prolong the life of pleated filter elements by soaking them overnight in a specially formulated Cartridge Cleaner every 3-4 months. You will, however, need backup pleated filter elements to install in your filter while your main pleated filter elements are soaking overnight. Read the instructions on the label before placing your pleated filter elements in a (5-gallon) bucket with a mixture of the Cartridge Cleaner and water.
- If pleated filter elements are torn or if the base is cracked, new pleated filter elements will need to be purchased, even if it they are less than 1 year old.
ADDING CHEMICALS: Once you have tested your chemicals and completed the maintenance schedule for that particular day, add the necessary chemicals from the previous test(s). Adding chemicals is an obvious part of your routine maintenance schedule.
WHEN TO SHOCK: "When" to shock is a question that is always asked, often eliciting numerous responses. In fact, "when" to shock the pool has been a constant debate in the pool industry. Some pool professionals will say once per week, some will say every other week, some will say monthly, and still others will say on an as-needed basis. One satisfactory answer given by a pool professional is that you only want to shock your pool when there is a build-up of ammonia and other undesired matter in the water that are handicapping the ability of your chlorine or bromine (or any other possible alternative) to effectively sanitize, disinfect and oxidize the pool water. Though a well-worded answer it does not effectively answer "when." Sorry to say, but there is no set, industry specific answer for pool owners as to when to shock. Relax-poolmanual.com will offer a general recommendation.
Shocking will vary due to the climate (primarily the temperature, humidity, and sunlight) and due to the bather load (the extent to which the pool is used-how many people use the pool at once, how many times throughout one day the pool is used, and how many days each week the pool is used). Here are suggestions:
- Cooler temperatures with limited use-every 2 weeks.
- Cooler temperatures with normal use-every 1 - 1½ weeks.
- Cooler temperatures with heavy use-every week.
- Seasonal temperatures with limited use-every 1½ - 2 weeks.
- Seasonal temperatures with normal use-every 1 - 1 ½ weeks.
- Seasonal temperatures with heavy use-every week.
- Hot/humid temperatures with limited use-every week.
- Hot/humid temperatures with normal use-every 6th day.
- Hot/humid temperatures with heavy use-every 5th day.
This is a guideline ONLY. With your climate and with your individual bather load, you may have to shock more often than these general suggestions (or perhaps less than these general suggestions). It is virtually impossible to determine "limited," "normal," and "heavy" use of the pool. It is also virtually impossible to determine an agreed upon value for "cooler," "seasonal," and hot/humid" temperatures for the numerous regions. You have to decide your "use" and your current "weather conditions" and make your own decision. Consult your local pool professionals in your region (climate) for their recommendations on shocking. Also, keep these points in mind:
- As climate and bather load alter, so should your shocking routine.
- The hotter the temperature, the greater the humidity, and the higher the bather load, the more often you will need to shock.
- If your pool professional recommends monthly shocking, get other opinions. Once a month may be viable in some regions, but this is in very few regions.
- Read the instructions on the label. Some manufacturers recommend first diluting shock in a bucker of water, while other manufacturers recommend broadcasting the shock straight from the packaging into the pool. When diluting, ALWAYS pour the chemical into a bucket that already contains water. NEVER pour water over ANY chemical!
